Telephony (VoIP) and mobile services

Being available by phone and managing calls are basic functions that need to be accessible in a user-friendly and reliable manner.

pascom – the ideal cloud PBX made in Germany

State-of-the-art VoIP solution built on the proven open source Asterisk technology. Incredibly reliable.

Consistent UX on all platforms with pascom

A fully-fledged client is also available for mobile phones, mobile first instead of second class citizen. The desktop client for Linux, Mac and Windows offers access to all functions.

Extensive pascom programming interface (API)

The powerful and well-documented RESTful API enables individually tailored integrations (e.g. connections to your self-developed software).

Telephony remains important

Even if other communication tools such as chats and video conferences are at the forefront in your internal communication, phone calls remain an important channel of communication, above all when connecting with customers.

Especially when it comes to offering end customer support at your company, telephony must be supported with effective solutions. CTI (Computer Telephony Integration) and VoIP (Voice over Internet Protocol) are indispensable technologies here, as is the connection to ticket systems or the like.

CTI allows for seamless integration of PBX into your work environment, enabling features such as call management, call logging, and screen pops on incoming calls. VoIP, on the other hand, is a technology that enables voice communication using network and Internet technologies.
